Undercut Bolts for Machine Alignment - Large Individual Bolts

In addition to world class laser alignment tools and shims, I&E Central also offers undercut bolts for the alignment of all sizes of machines. Sometimes referred to as "chicago bolts", undercut alignment bolts are designed to allow for additional horizontal movement of the machine base. This can solve the problem of a bolt bound alignment job.

We offer several options for you to purchase undercut bolts, both in sets and as packs of individual sizes.  Click here to view complete kits, or replacement kits of smaller bolts.

All of our bolts are manufactured to SAE J429 Grade 8 specification and come in a black oxide finish.  Bolts are manufactured in the US and will ship from either PA or NY.
